fix: sched: Change task_struct::state (v5.14)

See upstream commit:

  commit 2f064a59a11ff9bc22e52e9678bc601404c7cb34
  Author: Peter Zijlstra <email address hidden>
  Date: Fri Jun 11 10:28:17 2021 +0200

    sched: Change task_struct::state

    Change the type and name of task_struct::state. Drop the volatile and
    shrink it to an 'unsigned int'. Rename it in order to find all uses
    such that we can use READ_ONCE/WRITE_ONCE as appropriate.

fix: btrfs: pass btrfs_inode to btrfs_writepage_endio_finish_ordered() (v5.14)

See upstream commit:

  commit 38a39ac77e089515acbe85c6c70c3df1e728357d

    btrfs: pass btrfs_inode to btrfs_writepage_endio_finish_ordered()

    There is a pretty bad abuse of btrfs_writepage_endio_finish_ordered() in
    end_compressed_bio_write().

    It passes compressed pages to btrfs_writepage_endio_finish_ordered(),
    which is only supposed to accept inode pages.

    Thankfully the important info here is the inode, so let's pass
    btrfs_inode directly into btrfs_writepage_endio_finish_ordered(), and
    make @page parameter optional.

    By this, end_compressed_bio_write() can happily pass page=NULL while
    still getting everything done properly.

    Also, to cooperate with such modification, replace @page parameter for
    trace_btrfs_writepage_end_io_hook() with btrfs_inode.
    Although this removes page_index info, the existing start/len should be
    enough for most usage.

Disable x86 error code bitwise enum in default build

Only generate the bitwise enumerations when
CONFIG_LTTNG_EXPERIMENTAL_BITWISE_ENUM is enabled, so the default build
does not generate traces which lead to warnings when viewed with
babeltrace 1.x and babeltrace 2 with default options.
